Abstract
Provided is a ureteral stent (=50) including a bladder portion (=52) positioned in a bladder of a patient, a kidney portion (=54) positioned in a kidney and ureteral passageway of the patient, and one or more tethers (=56) coupling the bladder portion to the kidney portion. The ureteral stent allows urine to pass around a blockage, and allows a ureter orifice connecting the ureteral passageway to the bladder to move between a compressed state and an uncompressed state to prevent or minimize urinary reflux, flank pain, blood in the urine, etc., while allowing the bladder portion to move freely in the bladder to prevent the bladder portion from irritating the trigone muscle.
